Yes that time has come again. I shall be leaving tomorrow for a program which is already going on a very fast pace for different modules by some another persons. Lets see how things will go? Wish me luck and pray for me guys!

If you are working with Oracle than redo log files have a huge impact on the performance of the database. Its some times a huge pain how to attain an optimal size for the redo log files and the corresponding checkpointing and archiving frequency. One option is to find the redo generation rate of your database which is not so-easy option as it will keep on varying.  Second will be the sizing of the redo log files again which becomes a pain coz there is no rule of thumb( well 20minutes as per oracle) given for it. There is one parameter called Archive_lag_target which is described here in oracle docs.  This is given mainly for the dataguard configurations but Howard Rodgers has given a very good explanation for using it on standalone databases too on oracle forums.  It was a good learning to know about it. Here are some links of discussion if you are interested. How often should a database archive its logs Redo log switch Redo log size increase and performance Learning...

Some times, some wordings depict a true story. Those wordings touch you so deep inside that you can actually relate yourself to them. And if the matter is of love, if the matter is of broken hearts than that relation becomes more strong. Last whole night sitting on my pc , I was listening to this song sung by Romey Gill, Tutt Gaye Yarane . I don't like mostly the songs sung by him but this song and most importantly its lyrics are so fabulous that they kept me hooked all night. I shall explain the meaning of the song in English as the original song is in Punjabi. Listen the song and I am sure, even if you don't understand Punjabi, you will be able to feel the pain through the words of this song. Have a read: Lutt ke mohbbatan nu kiti hear feri ve, Tutt gaye yarane, jind fikran ne gheri ve! Hanjuan de saagran vich jindagi di beri hai, Dise na kinara koi maut aap hi saheri hai! Chhadd gaye mallah kiti minnat batheri hai, Tutt gaye yarane jind fikran ne gheri ve! Sar gayi...

Some times, there is always an another view of the most commonly occurring things. And that other view is always a little humorous. That's the same I read in the morning. It made me smile so I thought to share it with you all. Let me know how you find it? Have a read: Whenever I find keys to success, some one changes the lock. To error is human. To forgive is not "company policy". The road to success? It is always "under construction". Alchohal doesn't solve any problems. But if you think again, neither does milk. In order to get a loan, you first need to prove that you don't need it. All the desirable things in life are either illegal, expensive, fattening or belong to others. Since light travels faster than sound, people appear brighter before you hear them speak. Every one has a scheme of getting rich. Its just that it never works. If at first you didn't succeed, remove all the evidences that you ever tried! You can never determine tha...

I never thought that I would write a blog myself ever. To be really honest, I really didn't know what is a blog actually till so long. Still even after reading others blogs for some time, I never could convince myself that I can write too ( and I really am sure about this that my writing is no where to be called good now too) so I was always a little reluctant about having my own blog. Than way back in September 2005, my first blog post on Blogger  saw the sunshine. Again the color, theme all on the blog were picked coz of a reason and for a person. Than lot of things, people changed and I was like shaken from head to toe for some time( I am still not stable but trying my best to be) and there was a quietness over this space for nearly half a year till the time when I posted that I am still alive.  A lot was going on at that time which was enough to make me distracted and disturbed over lots of things and people. At that time Wordpress also was p...

Oracle has released its newest 11g database for windows platform.  So if you were waiting for it ( and I am sure you were) than your wait is over. Now the only worry of mine is to get that much fast net connection which can download 1.7gb of Oracle for me in 10 minutes ;-).

Tom Kyte  posted about Doug Burns's MEEP post . Moans from Miracle  is hosting this program for the sake of making better and knowledgeable Oracle professionals. I really like the concept and I really think Jan is lucky to get a chance to be in such kind of program. I am sure with all these people helping out him, he will surely do great! And I am just thinking that it would be really so much great if I ( and so many like me) too could have got a chance to be into such kind of a program when I was learning ( and still learning only) Oracle. Life would be really so much different I guess :)!

My sister who is a beautician, yesterday posed as a model for her company for the upcoming festival season's new bridal designs and make ups launched by her company. And her snap is published today  in the local newspaper . I wont say much except this that I am really proud on her and really happy for her. Congrats sis! Keep it up! You are the best!

Howard Rodgers  posted a question today on his blog asking that is it worth  for him to carry on with the Forum? The same thought is meant for the blog and some where for the complete site too. I am not sure how many in Oracle community can differentiate between "quantity" and "quality" as with the passage of time, there are just now too many sites, forums and blogs talking about Oracle and claiming to be an expert in it. But there are just a few and I mean really very few who are truly good. I wont name any one as I shall for sure miss so many from it but yes I would say Tom Kyte, Tim Hall , Howard Rodgers, Tanel Poder and the list goes on and on and on, these are some those people who are genuinely good, really want to help people to learn Oracle and are there always to help for the most tough questions asked ( and some times very basic questions too). I am saying this coz I do ask myself some times very very basic questions and some times some sensible ones. The...

Today is Dussehra (Vijayadashmi)  . In India, from this the festival season will begin. Dussehra is the festival of victory of good over evil. I wish and pray to God, all will have a very happy and prosperous year ahead and may God give you all his choicest blessings. Enjoy this day where ever you are with lots of sweets, crackers along with your family,loved and dear ones! Happy Dussehra to all of you!

Yes I am back. I don't know why but this trip was some thing which gave me a lot of troubles and tensions and that too right from the starting of it. Still some how I guess I am able to finish it up with a good note and that's what matters the most! This time there was a change in the travel plan as my manager had to come along with me. So he called me up and said that I need not to take bus as he would take me with him to his place and from there we would go. It sounded right so I said okay for it. Well if you know me already( if you don't than you must know now) than you know that I just hate people who don't value commitment and also are not punctual. I never let that happen in my best powers possible that I never get late from the scheduled time and no one has to wait for me. And I think that's the same that everyone else should do too. But as it is said one cant get all from this world and not all are same.  The same applies to some people who don't reall...

Yes I shall be leaving tomorrow for a very tough program. Though I had taken up this program already but all the time, it appears as a new and first time program. To add spice, I am doing it for some people who actually build the stuff than use it. Great! Lets see how it goes.  Pray for me guys!

Yes you read it right. That's what I asked how bad you are but here the good and bad are not for humanly nature but for how good/bad you think you are in your work. Tom Kyte  wrote about this very interesting article  which is saying exactly the same thing. I am in complete agreement with what ever is written there. To be really really good in some thing, one must always remember that there is just a little that he/she knows at the moment and learning never stops. That's why I believe that As our circle of knowledge expands, so does the circumference of darkness surrounding it. There will be always so much to learn and understand. The day when one starts thinking that he/she knows too much, from that point onwards, his/ her decay starts. A very nice and must read article!

In one of my last programs, we had to be face to face with ORA-00600 . Well its not a nice error message to see and that too when you had least expected it.  So what happened? Well our machines were not in the network. We didn't need the network too so we didn't bother.  In one of the discussions, there was a requirement that asked for network to be up. Those were Linux machines and students didn't know how to enable network over there. Well I know a little about Linux so I did make it enable and also enabled the use of DHCP  . Nothing seems to be wrong, network was up, internet also came up and Oracle was working fine. I would mention here that our /etc/hosts file was empty as the host information was not required and was picked up by DHCP. After one scenario, we needed to bounce the database. After instance startup, we were greeted with ora-00600[keltnfy-ldmInit],[46],[1]. Well ora-00600 is an internal error ( as it is told in the description also) and the ti...

Yesterday I received my success kit for clearing my Oracle 10g certification after about 4 months. Me and another friend of mine, Raghbir used to sit and joke around that Oracle forgot to send us our certificates even after its so long that we have written our exams coz of everyone at Oracle is busy celebrating 11g's launch parties and function :-). Well not exactly but the same kinda response I got from Oracle that they were busy and also systems who are responsible for the certificate dispatch were facing problems.  Cool!Well finally I have received my certificate.  There is not much difference in the 9i and this one.  Yes I like my card this time so much! So world, I am officially 10g certified now! And now time to look for 11g!

:) Yes I am back at home.  It was a tough program and it took a lot from my side to prepare and deliver it. I yet have to hear the official outcome of how I performed for which I am crossing my fingers but the verbal response was good.  So I have a positive hope.  Rest lets see what happens and comes in front. This was among the toughest and hardest programs and as I didn't get much time, it became really hard for me to prepare. Though I did prepare from books and spent so much time on searching and reading things from Google.But there are two people who really helped me so much on some of the toughest topics.  Without their help and guidance, I don't know how would I had covered those topics? These people are Tim Hall  and Howard Rodger . I must say that its not important to know everything but what's important is to make others understand and help them. And these 2 persons ( and all the other great persons whose names I am not mentioning here) are doing...

Hotmail  is among the oldest and most popular free email sites which are doing a great work. Since the time , Microsoft has bought it and with the new enhancement done, its really is much improved and stable. But now there is one more advertisement on the air which says that you are lost between the similar type of domains given to you for your personal mail id. Everyone is unique and the mail domain should reflect you. That's an another thing if you have your domain and you maintain your own web site. Well all wont have( and wont need too) so for that purpose, to give you an identity of your choice, Microsoft has now introduced  Coolhotmail  which will give you choice to pick your domain name which suits you and your personality. Cool thought I guess! So just go and check which domain suits you and pick that to get an email id which is just about you.  Did I pick one for me?Well yes I did and I am leaving it as a guess for you to find out what I would have picked f...

I just read this one in the mail and couldn't stop myself from sharing it here. Some times, even in few words, a lot is said and that's what this story says. Have a read: Once there was a boy. He always dreamed to be in love and be with that lady who would be his love of life. He never knew what it is to be in love but he always thought it would be the best thing that can happen to anyone. And as they say, if you wish for some thing truly it will come to you. He did fell in love(at least that's what he thought). He loved his lady more than anything else and thanked God that finally he has got what he always dreamed of. But there was some thing else that was written for him. One fine day, his love left him saying that she never loved him. And since that day he just used to sit and cry. One day, one of his friend said to him that he shouldn't be sad. It happens. The guy replied that tears come not coz of his pain but its for his love coz he has lost the one who ...

:) Yes I am not still back. I was supposed to be back today to home but some how I am told that a new assignment is there and there was no way to change its date.  Well there is no problem but just one issue is there that this is going to be among the toughest assignments that I have taken up till now. And to spice up things a little more, I have 2 days only to prepare myself for it. Great! What else I could ask for? Lets see how it goes now? Wish me luck guys. I really need your wishes!

Yes I am leaving tomorrow for a tough program. This is one of those programs which are short in duration but they are much harder than any other program. I hope I shall be able to make it go fine. Lets see what happens.  Wish me luck guys!
